Description

[Detailed description of the invention] (Field of industrial application) This invention is a door glass sealing device installed in an automobile, especially a hard-top vehicle that does not have a window frame for guiding the door glass (door sash) in the door. The present invention relates to the door glass sealing device for improving the sealing performance between the upper end of the door glass and a weather strip provided around the opening of the vehicle body.

(Prior Art) Among various types of automobiles, there is particularly a type of automobile that does not have a window frame for guiding the raising and lowering of the door glass 3 on the opening/closing door 2 screwed onto the side of the vehicle body 1, as shown in FIG. In a so-called hard-top vehicle, the upper edge of the door glass 2 is directly pressed against the outer surface of a weather strip 5 provided along the periphery of the opening 4 of the vehicle body 1 to prevent rainwater from entering the vehicle interior. A door glass sealing device is provided.

Further, the weather strip 5 installed in this type of conventional hard-top vehicle usually has a surface 5a that contacts and faces the upper end surface 3a of the door glass 3, and a surface 5a that contacts the inner surface 3b of the door glass 3, as shown in FIG. The opposing surface 5b is formed toward the side of the vehicle body 1,
Lifting and lowering of door glass 3 and door 2 as the window opens and closes
It is designed so as not to impede the horizontal movement of the upper end of the door glass 3 as it opens and closes.

(Problem that the invention aims to solve) However, generally when a car is traveling at high speed,
The door glass 3 is sucked outward by the air flow along the outer surface of the vehicle body 1, and a weather strip 5 is formed on the door glass 3.
The door glass 3 and the weather strip 5 tend to separate from each other, especially in hard-top cars where sufficient rigidity for holding the door glass cannot be obtained.
The problem was that the airtightness between the two was reduced, and a small gap was created between the two, resulting in wind noise.

Of course, in order to overcome the problem of reduced airtightness due to the above-mentioned suction phenomenon, the door glass 3 may be installed with the door 2 tilted toward the vehicle body 1 side, or the door glass 3 may be raised to a high position, and the weather strip 5 may be It is possible to increase the pressing force, but if you do this, when you open and close the door 2 with the door glass 3 raised to its highest position, the wind pressure may make it difficult to open and close the door 2, or the vehicle body may instantly collapse when the door is closed. In addition, when the air pressure rises and you feel pain in your ears, the weather strip 5 may appear at the top of the door glass 3 when you open or close the door.
There is a concern that it may be damaged due to strong friction.

This invention focuses on the problem of wind noise generated by door glass sealing devices in conventional hard-top vehicles, and controls the start/stop and rotation direction of the door glass drive motor that automatically raises and lowers the door glass. When the door is completely closed, the door glass is automatically raised to the upper limit position where the upper edge of the door comes into close contact with the weather strip, and when the door knob is pulled when the door is opened, the door glass is raised from the upper limit position. The door is lowered to a slightly lowered intermediate position, and when this is confirmed, the means for preventing the opening of the door is rendered inactive, allowing the door to be opened to avoid interference between the door glass and the weather strip, and This is an attempt to solve the above-mentioned problems.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained based on FIG. 1 corresponding to the embodiment.

The door glass drive means 16 built into the door of a hard-top vehicle is commanded to start, stop, and rotate through the control means 17 by operating a manual switch 26, and can stop the door glass at an arbitrary height. It's becoming like that.

Further, the control means 17 includes a door opening/closing detection means 27 for detecting the open/closed state of the door, a door knob detection means 24 for detecting whether or not a doorknob provided on the inner and outer surfaces of the door is being operated, Intermediate position detection means 23 is connected to detect when the door glass is at an intermediate position slightly lower than the upper limit position where the door glass is in close contact with the weather strip at the periphery of the vehicle body opening. Door opening prevention means 28 that prevents the rotation of the glass drive motor 16 and the opening of the door.
It is designed to control the operation of the

The control means 17 is configured to stop the rotation of the door glass drive motor 16 when the upper limit position detection means and the fully open position detection means attached to the intermediate position detection means 23 are activated due to the raising and lowering of the door glass. It's summery.

(Function) In the door glass sealing device of the present invention having the above configuration, when the door opening/closing detection means 27 detects the closing of the door at the time when the occupant gets into the vehicle or exits the vehicle and closes the door, the control means 17 activates the door opening prevention means 28 to lock the door, and also rotates the door glass drive motor 16 in the upward direction to raise the door glass to a position where its upper end is in close contact with the weather strip, and the upper limit position detection means When the door glass driving means is activated, the rotation of the door glass driving means is stopped. This allows the door glass to come into close contact with the weather strip, preventing wind noise during high-speed driving and water leakage during high-pressure car washing.

When the door is opened, when the occupant operates the doorknob, the control means 17 rotates the door glass drive motor 16 in the door glass lowering direction to lower the door glass to an intermediate position slightly below the upper limit position. , the pressing force on the weather strip is released, and when the intermediate position detection means 23 detects this, the door glass drive motor 16 is stopped, and at the same time, the door opening prevention means 28 is unlocked, so that the door can be freely opened. You can.

In this way, the upper end of the door glass can move horizontally without interfering with the weather strip, making the opening and closing operations of the door easier and preventing damage to the weather strip due to friction.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

In Fig. 2, 11 is the body of a hardtop car;
12 is a door hinged to the vehicle body 11; 13 is a slit formed on the upper edge of the door 12;
1, a door glass that appears and retracts from the opening 14 of the vehicle body 11; and 15, a weather strip provided around the periphery of the opening 14 of the vehicle body 11.

16 is a drive motor provided inside the door 12 for raising and lowering the door glass, and the drive motor 16 is connected to an electronic control circuit 17 provided on the vehicle body 11 side.
Start, stop and rotation direction are controlled by commands of
A pinion gear 18 fixed to the output shaft is meshed with an arc-shaped rack gear 21 of a known door glass lifting mechanism 20 consisting of two link members 19 and 19', and the door glass 13 is moved along two guide rails 22 and 22'. Its upper end 13a is the weather strip 1.
The vehicle window is raised and lowered between an upper limit position (a) in which the vehicle window is pressed into close contact with the vehicle window and a fully open position (c) in which the vehicle window is fully opened.

23, the door glass 13 is moved from the upper limit position A to 3.
An intermediate limit switch 24 detects when the door 12 is at an intermediate position lowered by ~10 mm.
26 is a manual switch for raising and lowering the door glass provided at an appropriate position around the seat; 27 is a manual switch for raising and lowering the door glass; 27 is a manual switch for raising and lowering the door glass;
2 is a door switch that detects whether or not 2 is completely closed, and each of these switches 23, 2
4, 26, and 27 have the role of transmitting detection signals and operation signals to the electronic control circuit 17.

Reference numeral 28 denotes an electromagnetic lock provided around the entrance of the vehicle body 11. The electromagnetic lock 28 operates a solenoid based on a command from the electronic control circuit 17 to cause a lock pin to move in and out to open the door 12. The opening timing of the door 12 is determined so that the door 12 is in a disabled state or in an openable state.

Note that the electromagnetic lock 28 is used in conjunction with a normal door lock device, and the door lock device is connected to the door 12.
When the door 12 is locked, the door 12 will not be opened even if the doorknob 25 is pulled. Further, when the door glass 13 reaches the upper limit position A or the fully open position C, the door glass drive motor 16 automatically activates a limiter (not shown) due to a change in the current, as in the case of a conventionally known power window device. It's starting to stop.

On the other hand, when the door glass 13 is at the upper limit position A indicated by the solid line as shown in cross section in FIG.
It integrally has protrusions 29 facing each other,
The upper end 13a of the door glass 13 is designed to fit into the groove 30 of the weather strip 15, and when the upper end 13a of the door glass 13 has descended to the intermediate position B shown by the two-dot chain line, it is possible to prevent the door glass 13 from being exposed to rain or washing with a hose. etc., exhibits sealing performance to the extent that water does not leak, and does not interfere with the horizontal trajectory (indicated by arrow Y) of the upper end 13a of the door glass when the door is opened and closed.

The operation of the door glass sealing device of the present invention having the above structure will be explained based on the flow chart shown in FIGS. 4a and 4b.

First, when the occupant closes the door 12,
As shown in FIG. 4a, when it is confirmed in step 1 that the door switch 27 has completely closed the door 12, the electromagnetic lock 28 locks the door 12 in step 2, and then in step 3 the door glass drive motor 16 is activated to raise the door glass. direction. As a result, the door glass 13 has its upper end 1
3a rises to the upper limit position A and stops when it is pressed against the weather strip 15 and the limiter is activated, which improves the sealing between the door glass 13 and the weather strip 15, reducing wind noise during high-speed driving and water during high-pressure car washing. Leakage etc. are prevented.

Next, when the occupant attempts to open the door 12, the doorknob 25 is pulled in step 4 as shown in FIG. 4b. When the doorknob switch 24 detects this and turns on, the door glass drive motor 16 is In step 5, it begins to rotate downward, and in step 6, it continues to rotate until the intermediate limit switch 23 is turned on, and when the intermediate limit switch 23 is turned on, it moves to step 7.
The electromagnetic lock 28 is turned off to make the door 12 openable. Therefore, when the occupant operates the doorknob 25, the electromagnetic lock 28 first lowers the door glass 13 to the intermediate position RO with the door 12 locked, and after confirming that it has been lowered to the intermediate position RO, the electromagnetic lock is activated. In order to unlock the door glass 28, the upper end of the door glass 13 is connected to the weather strip 1.
It moves horizontally outward without interfering with the protrusion 29 of No. 5, prevents damage to the weather strip 15, and facilitates opening and closing of the door 12.

Note that when the door 12 is closed and the door switch 27
When the door is detected as closed, the door glass 13 can be raised or lowered between the upper limit position A and the fully open position C, regardless of the intermediate limit 23, by operating the manual switch 26 to the upper or lower side. However, when the door 12 is opened and the door switch 27 detects the open state, even if the manual switch 26 is operated in the upward direction, the drive motor 16 will not start when the intermediate limit 23 detects the position of the door switch 13. stops and is prevented from rising to the upper limit position A.

Also, when the door lock device is activated,
Even if the doorknob 25 is pulled, this automatic circuit does not work.

(Effects of the invention) As described above, the door glass sealing device of the present invention uses a control means to control the start/stop and rotational direction of the door glass drive motor that automatically raises and lowers the door glass, and when the door is closed. When the weather strip is closed, the door glass drive motor is rotated in the upward direction to move the upper end of the door glass to the upper limit position and press it against the weather strip to improve adhesion.
When an attempt is made to open the door by operating the doorknob, the door glass drive motor is rotated in a downward direction to move the door glass from the upper limit position to an intermediate position slightly lowered to maintain close contact with the weather strip. Since the door can be easily opened and closed by minimizing the phenomenon, even if the door does not have a window frame and the glass retention rigidity is insufficient, it can greatly improve the sealing performance between the door glass and the weather strip when the door is closed. This makes it possible to improve the door glass sealing properties of hard-top vehicles by preventing wind noise and rainwater from entering during high-speed driving, as well as preventing wash water from entering during high-pressure car washes. It has an excellent effect.

Moreover, according to the present invention, when the door is opened/closed, the door glass can be lowered slightly to prevent damage to the weather strip. It is also expected to have the effect of preventing a rise in air pressure and improving the ease of opening and closing the door. Further, according to the present invention, the position of the top edge of the door glass is changed when the door is opened/closed and when the door is fully closed and locked, so that the closeness between the top edge of the door glass and the weather strip is automatically changed. Therefore, unlike conventional weather strips, you are not forced to make an unreasonable design, and it has the effect of increasing the degree of freedom in designing the door area and seals of the vehicle body.
